If you are completely foraging your food you would need to eat like ridiculous quantities of food, several pounds of tubers, fruits, greens and lean protein. You need concentrated sources of energy, and nuts provide that by the bushel. And they store very easily as long as you keep them away from rodents. Almost 3,000 calories per pound for walnuts and hickory nuts. And the wildlife around big nuts are bigger too. In a conifer forest with only tiny seeds you get small red squirrels that you'd need to eat 25 of a day to get enough calories. In larger nut woods like oak hickory in the US, you get much bigger gray and fox squirrels where only a couple a day will feed you. Not to mention all the other wildlife benefits from hard mast. If you are down in tropical areas with coconuts, that's a golden ticket to survival. I'm not too familiar with other tropical nuts but there's many. Far north doesn't have anything, except some areas have hazelnuts, Siberia has some larger pine nuts.
Look for places with nuts, learn all you can about the nuts, consume the nuts.
